Symptoms & Treatments of Sea Lice

Symptoms of Sea Lice
The most common symptoms of sea lice include an intensely itchy red rash with small blisters and elevated areas of skin. These painful and unsightly lesions may appear anywhere on the body but are often concentrated in areas covered by swimwear as large numbers of larvae often become trapped in these regions.

Skin irritation, redness and welts usually appear several hours after attack. Pain and irritation can last two days to two weeks, sometimes accompanied by fever and nausea.

Severe reactions to sea lice exposure may include fever, chills, headaches, nausea and vomiting, especially in children.  In rare cases, extreme allergic reactions may require hospitalization.

In most cases symptoms appear after 6 to 9 hours from initial sea lice encounter.
